T all whom it may concern:

Be it known that I, SIDNEY D. WALDQN, a citizen of the United States, and resident of Detroit, lVayne county, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the following is a specification. This invention relates to hydrocarbon motors, and particularly to the means for controlling the oiling system thereof.

Heretofore oiling systems have been employed on hydrocarbon motors in which there are a main oil feed to the principal bearings of the motor and an auxiliary oil feed which gives an extra supply of oil to the motor or in some cases feeds the oil direct to the cylinder walls. The auxiliary oil feed is usually adapted to become operative when the motor is running at high speed or is pulling hard. None of the oiling systems heretofore employed, however, have any provision for increasing the oil supply or oper-` ating the auxiliary feed when the motor is cold, as when starting, or for cutting down the oil feed or closing the auxiliary feed when the motor is hot or is running under normal conditions. After a motor has been standing for some time and has become cold, most of the oil has ofcourse drained from the bearings into the crank Oase and it is very desirable, therefore, that an unusual supply of oil should be fed to the various bearings of the motor as it is started under these conditions. This unusual supply should of course be out down as soon as the motor has started or has warmed up so that it is running normally.

It is one of the objects of the present invention to provide means for i feeding an unusual supply of oil to the motor under the above referred to conditions of starting, and to make such means substantially automatic in its action. f

.Another object of the invention is to provide an auxiliary oiling system for a hydrocarbon motor, which system shall be controlled both by the means which control the richness of the mixture passing to the motor valve of the motor.

Other objects of the invention will be apfor controlling the throttle parent from the following description taken in connection with the drawings which form a part of this specification, and in which Figure l is a side elevation of a motor embodying this invention, having parts cut away to illustrate certain interior construction; F ig. 2 is a slightly enlarged view of most of the operating parts shown in Fig. 1 and illustrating these parts in a different position; and Fig. 3 is a sectional view through the oil valve.

Referring to the drawings, represents a motor base or crank case upon which are mounted the cylinders 11, in the present case six cylinders formed in three castings of two cylinders each. These cylinders are supplied with a combustible mixture through a manifold 12, an intake pipe 13 and a carbureter 14. In the intake pipe 13 is a throttle 15 which is under control of an accelerator edal 16 connected to the throttle by a rod 1 the accelerator pedal being mounted on the inclined floor board 18 in convenient position for operation by the drivers foot. The throttle is held yieldingly in substantially closed position by a spring 19, the arm 20 of the throttle resting against an adjustable stop 21 which determines its substantially closed position for idling the motor.

The carbureter 14 has a main air inlet 22 and an auxiliary air inlet 23, the former being controlled by a butter-ily valve 24 which is normally held in wide open position, and the latter being controlled by a spring pressed poppet valve 25, the spring 26 of which is adjustable byv a wedge 27 controlled by a rod 28. The valve 24 is controlled by a rod 29 and spring 29 and both rods 28 and 29 may be operated in any suitable manner as by the control rod 30 which extends upwardly parallel with the steering column 31 and is moved longitudinally as by a hand wheel 32 through rack and pinion mechanism 33. It will be seen that if the rod 30 is moved downwardly it will carry the bell crank 34 with 'it to thereby move the wedge 27 forwardly and increase the tension on the spring 26, and a further movement of the rod 30 carries with it the bell crank 35 and thereby moves the butter-Hy valve 24 to closed position. The position of this rod 30 therefore determines the adjustment of the carbureter for increasing and decreasing the richness of the mixture, it being obvious that when the valve 24 is closed and the tension on the spring 26 increased, very little air will be drawn into the carbureter and the consequent suction will draw in considerable gasolene through the spray nozzle. This position of the carbureter is shown in Fig. 2 and it may be termed the starting position of the motor. In Fig. 1 the carbureter` is shown in normal 'or running position, that is, with the valve 24 Wide open and the wedge 27 adjusted so that the spring 2G has 'a very light tension on the auxiliary air valve 25.

The lower part of the crank case 10 forms an oil sump or well 36 to which the oil drains from the various bearings within the crank case. Operating in the bottom of the sump 36 is an oil pump 37 which takes the oil from the sump and forces it under pressure through a pipe 3S to a strainer 3 9 and from thence to a manifold 40 which extends longitudinallyT of the motor and is provided with feed pipes 41 which lead to th'e various main crank shaft bearings 42 of the motor. From these bearings the oil may be led to the crank pin bearings 43 vas shown in sec- 'tion in Fig. 1, and all excess oil thrown off from the bearings returns to the sump 36, thus giving a constant circulation of the oil. Another pipe 44 leads from the manifold 40 to a valve 45 which' may be of any suitable form and is operated by a stem 4G which is shown in bifurcated form so that it may be operated by two independent devices. It will be understood that thevalve 45 is closed by a spring 45 as shown in Fig. 3 and is opened by pressing the stem 46 inwardly against lthe action of the spring. i

A pipe 47 leads from the outlet of the valve 45 and forms-an auxiliary manifold 48r which also extends longitudinally of the motor and has branch feed pipes 49 which may nlead to any desired points of the motor to which an'extra supply of oil-may be fed andthese pipes are shown in the drawings as leading directly to the 'cylinder walls.

Under these circumstances, therefore, it will be seen that when the valve 445 is opened,

oil will be fed under pressure to the auxil iary oil manifold 48 and from ythence conveyed directly to the pistons'of the motor which operate in the cylinders. This oil will also drain back into the sump asin the l main system. y v

As above suggested, the auxiliary oiling system isiy intended to be used only when the motor is developing considerable power or is running at high speed, or when themotor is cold as when starting. Therefore the present invention provides that the valve 45 may be operated either by a connection from the from the carbureter control means so that the valve 45 is opened when the carbureter is adjusted for starting the motor or keeping it running until it is warmed up. The first mentioned connect-ion is in the form of an arm 50 which has an adjustable button 51 thereon and is arranged in the path of one of the branches of the stem 46 so that the latter is operated when the accelerator pedal 16 is depressed to open the throttle- The other connection, which is independent of the irst mentioned connection, is in the form of a pivoted arm 52 having an adjustable button 53 thereon for operating the stem 46, and this arm 52 is moved in unison with the carbureter control devices through a connecting rod 54 which connects the arm 52 with either of the bell crank levers 34 or 35, being shown connected to the lever 34 in the form of the invention shown herein.

From the above it will be seen that the valve 45 will be opened as the throttle 15 is opened, or it will be opened as the carbureter 14 is set for the starting position of the motor or for running the motor when cold. Thus the position of the valve 45 is determined eitherby the throttle position or by the richness of the mixture passing through the carbureter. Also it will be seen that the .means and said mechanism whereby the supply of oil to the motor cylinders is cut olf when the carbureter air valve is opened.
